The object of my invention a COHSUHC tion by reason of which a better CGK'l'iilOl oml diffusion of the combustible vapor infirm (lnccd is obtainecl, as also greater cccessi bility of the gas conveying}; pipes; for clean ing annl repair.

By raising and lowci ing flow of 2111 be occiiimtoly and by allowing the valve to fall the vertical fine (i all oil: the soot in the finc may be quiclil gr removed Without any material inicrn ption in the supply of As a means of coL looting; the soot removed from the vertical fines G, a basin R is provided under-each flue. To facilitate cutting out the burner lube H, a. damper S is proviclc in each vertical flue The door T may then be opened and a camper introduced into the burner and the soot removccl. Any other suitable may be cmployccl for removing the sooi".

Tlic advantage of tho construction dis closecl. founcl in Tlho fool, that the supply can be exactly rcgulctccl, irrespective of the pressure at which the is; supplied to the ltiln, and illw 1n z'ooucccl into the comlmc'cion chambers in such manner as to bring 'obonl. a perfect mixture with the heated air and free. burning obtained will out llic gaseous vapor impinging upon the, walls oi? the chambers. llItllEI'. the objection of clog ing of tho supply tubes common in furnace construction, is entirely (lone away with through the ii'istrumcn'mlity of tlic falling wciglitccl valve, which keeps the passngcs clean.

Having lions c cascribccl my invention, I claim:

1. in. a tunnel kiln and in combination Wll'll 'lalic combustion chambers, gas burners projecting into the combustion chambers through the sides of the latter and mlapitccl in nojcc supply of gas in a horizontal direction along tho combustion chambers, gas supply fines located exterior to the kiln om} conncciccl to the burners, and gas regulating valves between said supply fines and burners.

2. in a tunnel kiln and in combination 'itli the combustion chambers, burners projecting into the combustion chainbcrs cin-ougli the sides of the lattcr cncl adopted pvojeccing laterally ii'ilo the comlmstion chambers and adapcecl to oel:- a.- supply of gas in a horizontal dir 'tion along the combustion chambers, vertically disposed supply lines located. exterior to the is]: and conncciecl to the burners, weiglil'ecl gas regulating valves situated in the vertical supply llues, together with means whereby said Valves may be movcol to vijsgulzitc the supply of gas and allowed. to (hop "to remove accumulations in the vertical lines.

A. In tunnel kiln and in combination with the combusl ioliychambers, bm'i'wrs projecting laterally" into flue combustion chambers and mlapteil to project a supply of as iii ;1 horizontal direction along size comlmstion chsn'ilrei-s, verlzicslly disposed supply fines lOCllfiGd exterior *to the kiln and connectedv to she burners, gals regulating valves between said gas fines and said burners, said gas regulating valves having the shape of 21 'tm 110M186}. cone, together vi ch means ior llftmg and lowering seicl valves to regulate we gas supply mnl also permit movement of said cones lhrou the vertical fines in remove accun'iulstiojns in said fines.

5. In a tunnel kiln and in. combination Willi the conilmscion clismlz-ei's, gas burners in" jocizing into the comliuslzioii, chambers tlnrough the sides of the latter and adopted i0 project a supply of gas ima horizontal (lii'ccion along the combos on chambers, vertical 2 supply fines located exzlevioi' to the .lilli";,2i1'll connected to the biiu'iiers, gas regulating valves between said gas supply lines and. said burners and {lmnpevs in said verticall'lues below the buriicis in a timnel kiln and in combination with the combustion chambers, 12, l1orizontally disposed flue located below the chhmbers and the bottom of llllfi kiln, vortically disposed fines conncctedl to said horiwonlzal flue and located exterior to the kiln gas lJF-J'DAJZS connected to said vertical fines projecting inwardly tliroiiigli the wells of the kiln and con'iliusi ion. zidaptecl to discharge in fv'lie interior of the combustion chambers in a loz'igiiiudirml direction, gas regulating valves interposed between the vertical iues and the gas pipe, and means for controlling the movement of such valves.

In testimony whereof, I fl-i'liK my signsmire.
